1'0 all whom it may concern: I

Be it known that I, ALEXANDER J. DAPRON, a citizen of the United States,and a resident of Prairie du Rocher, Randolph county, Illinois, haveinvented certain new and useful Improvements in Window-Screens, of whichthe following is a specification containing a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to a window-screen; and the object of my inventionis to construct a window-screen that is adjustable vertically andlaterally.

My invention consists of four screen-sections arranged upon one anotherso as to be adjusted both vertically and laterally and means arrangedupon the side rails of the screen for locking the sections together atdifferent points in their vertical adjustment.

My invention'further consists in certain new and novel features ofconstruction and arrangement of parts that will be hereinafter setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which Figure 1 is a front elevation of my improved screen,the same being adjusted into a small compass. Fig. 2 is an edge View ofthe screen seen in Fig. 1. Fig. 3 is an elevation of the screen, showingthe sections adjusted laterally and vertically and fitted into the lowerportion of a window, as required for use. Fig. 4 is an enlarged verticalsection taken on the line 4 4 of Fig. 3. Fig. 5 is an enlarged verticalsection taken on the line 5 5 of Fig. 3. Fig. 6 is an enlarged plan viewof the screen. Fig. 7 is a horizontal section taken on the line 7 7 ofFig. 3. Fig. 8 is a horizontal section taken on the line 8 8 of Fig. 3.

In Figs. 1 and 2 the views are supposed to be taken looking against theinside of the screen, and in referring to the individual sections of thescreen hereinafter they will be referred to as the upper and lowerright-hand sections and upper and lower left-hand sections. There arefour of these sections, all equal in area and of approximately the sameconstruction.

The lower right-hand section comprises a side rail 1, a top rail 2, abottom rail 3, and the wire-screen section 4, which is secured to theouter faces of these three rails, and the left-hand edge of thescreen-section is bound by a strip of sheet metal 5. Formed integralwith the outer face of the side rail 1 is a vertically-extending rib 6.A locking-finger 7 is pivotally held between ears 8, fixed to the innerface of the side rail 1, the upper end of which finger is extendedhorizontally through an aperture 9, formed in the upper end of saidtheunder side of the top rail 2, and sheetmetal clips 16 are secured to theends of the rails 2 and 12 and pass around the bodies of the adjacentrails. Similar clips 17 are secured to the ends of the lower rails 3 and13,

which clips pass around the bodies of the ad' jacent rails. Secured atone'endv to the clip at the outer end of the rail 13 and at the oppositeend to the lower end of the rail 11 is a thin metallic strip 18, thelower edge of which occupies the same plane with the lower edge of therail 3. This last-mentioned strip 18 is for the purpose of closing thespace which is formed when the left-hand end of the rail 3 moves awayfrom the lower end of the rail 1 1. Formed integral with the outer faceof the rail 11 is a vertical rib 11 and pivotally mounted between ears11 on the inside face of the upper end of the rail 11 is a lockingfinger11, the point of which is bent laterally and passes through an aperture11 formed in the upper end of the rail 11, and beneath the lower end ofsaid locking-finger is positioned a spring similar to the spring 10.

The upper right-hand section comprises a vertically-arranged side rail19, a top rail 20, a bottom rail 21, and a wire-screen section 22, whichis secured to the front faces of the rails just mentioned and beingprovided on its left-hand edge with a metallic bindingstrip 23. Formedin the inner face of the side rail 19 is a groove 24, in which rides thetongue 6 of the rail 1, and formed in the face of said rail 19 adjacentthis groove 24 is a series of teeth 25, with which the point of thelocking-finger 7 engages.

Retaining-clips 26 are secured, respectively, to the upper and lowerends of the side rails 1 and 19, which clips engage around the adjacentportions of the bodies of said side rails 1 and 19.

The upper lefthand section of the screen comprises a vertically-arrangedside rail 27, which rides immediately against the rear face of the rail11, the top rail 28, the bottom rail 29, and the wire-screen section 30,which is secured at its edges to the rails just mentioned and whichslides outside the wirescreen section 22 and being provided along itsright-hand edge with a metallic bindingstrip 31. Formed in the innerface of the rail 27 is a groove 32, in which travels the rib 11 andformed in the face of the rail 27 adjacent this groove 32 is a series ofteeth 33, with which the point of the locking-finger 11 engages.

Secured to the upper end of the rail 11 and to the lower end of the rail27 are clips 34, similar to the clips 26, and which pass around adjacentportions of said rails 11 and 27. Fixed to the outer ends of the rails20 and 28 are clips 35, which pass around adjacent portions of saidrails 20 and 28. Secured at one end to the clip on the outer end of therail 28 and at its opposite end. to the upper end of the rail 27 is athin metallic strip 36, the top edge of which occupies the same planewith the top edge of the rail 20, and which trip is for the purpose ofclosing the space formed when the rail 20 is drawn away from the upperend of the rail 27.

WVhen a screen of my improved invention is adjusted laterally to fit ina window, it is only necessary to grasp the side rails of the sectionsof the screen and move the same away from one another, and in so doingthe corresponding pairs of rails 3 and 13, 2 and 12, 21 and 29, and 20and. 28 will slide outwardly past one another until the screen is of theproper width. As there is no weight or pressure laterally upon thescreen, it is not necessary to lock the sections against lateralmovement, as the friction between the various clips passing around thehorizontal rails of the screen is sufficient to retain the screen in anyposition to which it is laterally adjusted. To adjust the screenvertically, the lockingfingers 7 and 11 are manipulated so as that theirupper ends are disengaged from beneath the teeth 24. and 33, and theupper right and left hand sections of the screen are now moved upwardlyrelative the lower righthand and left-hand sections, and when. thescreen has been extended vertically to the desired point thelocking-fingers 7 and 11 are disengaged and the points thereof willreengage beneath the teeth 24 and 33.

Thus it will be seen how I have constructed a simple and inexpensivescreen that may be adjusted laterally and vertically so as to fit anywindow of ordinary size, and which screen is adapted to be looked afterbeing vertically adjusted, so that the weight of the window on top ofthe screen cannot close the screen after it has been properly adjusted.

I claim 1. In a window-screen, a series of rectangular frames,wire-screen sections secured to each frame, connections whereby saidframes are held together and adapted to be adjusted vertically andlaterally, and locking-fingers carried by the lower pair of frames andadapted to engage with theupper pair of frames; substantially asspecified.

2. In a window-screen, a series of rectangular frames, wire-screensections carried by said frames, means whereby the frames are heldtogether and permitted to slide vertically and horizontally, there beingteeth formed on the inner faces of the side rails of the upper pair offrames, and locking-fingers carried by the side rails of the lowerframes for engaging said teeth; substantially as specified.

3. In a window-screen, a pair of rectangular frames, wire-screensections carried by said frames, there being notches formed in the facesof the side rails of said frames, means whereby said frames are held tomove laterally relative one another, a second pair of frames,wire-screen sections carried thereby, means whereby said second pair offrames are held to move laterally relative one another, means wherebythe second pair of frames move vertically relative the first pair offrames, and locking-fingers carried by the side rails of the second pairof frames and adapted to engage in the notches formed in the side railsof the first pair of frames; substantially as specified.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
